Prayer is a conversation with God, like talking to one's mother. It is an expression of love and gratitude to God. We should pray to earn God's grace and for internal cleansing. While God knows our problems, we should still ask God for help through prayer when needed. It is our duty to pray and put our thoughts into sincere words. We can pray at different times like morning, night, before eating or working. Complete surrender to God's will through prayer can provide peace of mind.
